What is the Best Rifle Scope for a .308? – Buying Guide and Reviews

Winchester introduced the .308 Winchester in 1952. Since then it has grown into one of the most popular hunting cartridges around the globe. With some minor changes, it even morphed into the 7.62 NATO which is close.

Today the .308 can be found in many modern hunting rifles. It is a popular choice for hunters that require high-quality optics. We’re having a closer look at the best 308 scopes that you can find.

Hunting or shooting with a 308? Check our list to find the top riflescope for your .308.

Before looking at these hunting optics, let’s have a closer look at the rifles. The .308 specifies the diameter of the bullet. This certainly means that a rifle shooting a bullet with this diameter must have a matching bore.

The confusing part is that the .308 rifle designation means to use a specific cartridge. There are other types of ammunition that use a .308 diameter but where the cartridge is different.

An example is the .30-30 Winchester Model 94. The bullet diameter is .308 inches in diameter but it’s not a .308 rifle. The cartridge for the .30-30 is different and is specifically geared for long-range shots.

You might wonder why this is important to point out. The reason is that the scope you’re looking at needs to match the rifle and the type of shooting performed with it.

What is the Best Range for the 308?

The .308 is useful for short, medium, and long-distance shooting. This means you would want a scope that works for those situations.

One other thing to remember is that the .308 is often used for tactical shootings. That’s why some top-notch scopes for this cartridge are also known as sniper scopes. This does in one way mean that you couldn’t use such a scope for hunting big game.

Nikon is known for its high-quality glass and overall scope construction. The M-308 is no exception to this. The tube sports a 1″ diameter and is made from aluminum. The glass is fully multi-coated and allows up to 95% light transmission.

The magnification range is more than enough for medium to long-range shooting. The objective lens is large enough to allow a lot of light to get into the scope.

They equip the Nikon M-308 with a fast focus eyepiece that enables you to quickly acquire your target. The .308 has a bit of recoil and the scope could need a little more for eye relief. The eye relief ranges from 3.7 to 4 inches and it would not hurt to have a little more.

The field of view at 100 yards is 6.3 – 25.2 feet depending on the magnification settings. The adjustment range for windage and elevation is 40 MOA. This can end up being a little on the low side when you’re performing a real long-range shot as you might run out of adjustment range.

The Nightforce SHV 5-20x56mm is a great long-range optic. The very large objective lens provides superior light penetration into the tube and makes it our pick for the best low-light scope for 308 rifles.

You get a scope with ultra-clear glass and multi-layered coatings. There’s basically no better image you can get from any other scope on the market.

There’s no clear winner in this comparison. Each of the scopes shown has its strengths and weaknesses.

The Nikon M-308 might overall be one of the best scopes as it has a wide range of scenarios in which it can be used on a .308. However, Nikon only lists this scope in the ‘Archived’ section which means it’s not built anymore. You can still find it online and at retailers though.
